HOT-WATER HEATING UNIT.

Application filed March 11, 1918, Serial No. 221,660. Renewed May 10, 1922.

Z '0 all "who/n it may concern.

lie it known that I, HERMAN Esonnn'r, a citizen of the United States, and resident of the borough of mucous, city of New York,

in the county of Queens and State of New York, have invented certain new and useful Hotater Heating Units, of which the fol lowing is a. specification.

This invention relates to improvements in hot-water heating apparatus for apartments, rooms and the like, andniore particularly to that type of such apparatus in which each radiator unit has self-contained means for supplying water and burning fuel, and means for circulating the water. The primary object of my invention is to produce a construction of hot-water heating-unit which will provide means for causing an efiicient, effective and uniform circulation of hot-water throughout the area. of the entire unit, and will thus produce both quick-acting and uniform water-heating and radiation.

Another object of my invention is to pro- 5 duce a unit which will not only be inexpensive in construction but will provide expansion and filling means extending transversely acrossthe circulating tubes in a sub stantially horizontal plane along the top of the unit, whereby compactness of construo tion is procured.

Still another object of my invention is to provide in such a hot Water heatingunit, a gauging device for determining when the water supply should be replenished.

In the accompanying drawings, in which similar reference characters designate cor responding parts throughout the several views, V I

Fig. 1 is a vertical section throughthe longitudinal axis of a radiator unit embodying my invention; and

Fig. 2 is an end elevation of the unit shown in Fig. 1.

Referring now to these drawings, 1 indicates a radiator unit comprising a series of vertically-disposed tubes, pipes or radiator sections which are interconnected at their upper and lower ends. Preferably the tubes 2 communicate at their lower ends with a boiling or heating chamber 3 and the adjacent walls of the tubes 2 diverge outwardly at their bottom portions to form wedge-shaped terminals 2 within the chain:

ber 2}, so as to present as slight resistance as posslble to the circulation or passage of the water upwardly within the tubes 2. The chamber 3 as shown is frustro-conical in cross-section, having a substantially flat bottom 3 and sides inwardly converging therefrom which merge or connect with the straight vertical edges of the tubes 2. At their upper ends, said interconnected tubes, as illustrated, communicate with a connecting or filling chamber 4.

A return 5 has a connection with said in terconnected radiator tubes at one side of the upper end thereof, is disposed to extend transversely of said series of tubes and has a connection with'the lower end of said tubes'at the side opposite to the said upper connection; As'shown in the drawing, this return pipe 5 has, at its upper end, a return or U-connection 5 communicating with one end of the connecting chamber l, from which connection the said pipe traverses the-rear-side of the radiator unit diagonally and has at its lower end another return or U-connection 5 which extends below the bottom plate 3 of the boiling chamber and .connects vertically therewith at the side of the radiator unit opposite to the first-mentioned connection. 7

The radiator unit may be heated by any suitable fuel, the heat being applied however at the bottom of the boiler and below the radiator tubes 2. As illustrated gas burners .6, 6 ,.which may be of any suitable type, are supplied by, a supply pipe 7 supported on brackets 8, 8 suspended from the bottom plate.

The unit is. filled with water through a pipe 9 which is disposed transversely of the said tubes in substantially a horizontal plane along the top of the unit, and has at its free end afilling cup 10 whichopens'upwardly to the air. The pipe 9 is, as shown, supported by brackets 9 9 in a sufliciently inclined position to furnish sufiicient pitch to cause the water to flow readily through the same into the radiator unit, but to hug the top of the radiator as closely as possible 7 so as to be out of the way.

The pipe 9 is of suflicient diameter to permit the water in the unit to expand within the same, when heated, without overfiow.

A transparent gauge 11 is also preferably water requires replenishment.

'having a connection with saidconnecting chamberat one end, extending diagonally nation, a

bination,

The operation of the device is as follows:

The unit is filled with water through the cup 10 and pipe 9 till it shows in the indicating gauge 11 and the gasis lighter. The water within the boiling chamber 3 is thus heated and within an exceptionally short period of time, complete circulation begins. The hot water rising through the tubes creates a suction through the vertical U-connection below the boiler plate and simultaneously forces the water in the boiling compartment upwardly through the tubes 2 into the connecting chamber and thence through the; upper end of the return pipe and down through the same to the said vertical connection. It will be seen that the disposition of the pipe 5 diagonally across the tubes 2 will, in view of the application of the heat below the boiling chamber plate 3*, cause auniform circulation throughout of the area of the tubes; v

Furthermore, when the water is heated, it will have 'suflicient space to expand within the pipe 9, and in thenormal operation of the device, the gauge 11 should always be full or partially filled with water.

Having described my invention, I claim: 1. A radiator .unit, embodying, in combiradiator tubes, with each of said tubes at the bottom thereof, a connecting-chamber communicating with each of the said tubes at the top, a

return-pipe having a connection with said connecting-chamber at one end, extending diagonally across the said tubes and havin at the end of the unit opposite to the first mentioned connection; means for heating water in the unit, and means for filling the unit with water and providing space for the expansion thereof underrheat.

2. A radiator unit, embodying, in coma series of vertically-disposed tubes, a boiling-chamber connected with each of said tubes at thebottom thereof, a connecting-chamber communicating with each of said tubes at the top, a return-pipe wedge-shaped terminals series of vertically-disposed a boiling-chamber connected a connection with the boiling-chamber across the said tubes and having a verticallydisposed connection with the bottom-plate of said boiling chamber at the end of the unit opposite to the first-mentioned connection; means for heating water in said boiling chamber, and means for filling the unit with water and providing space for the expansion of the water under heat.

8. A radiator unit embodying, in combination, a series of vertically-disposed radiator tubes, a boiling-chamber connected with each of said tubes at the bottom thereof, a connecting chamber communicating with each of the said tubes at the top, a return pipe having a connection with said connecting chamber at one 'end of the unit, extending diagonally across the said tubes and having a connection with the boiling chamber at the opposite end of the unit;

between said vertically-disposed radiator tubes 'within the boiling-chamber means unit for heating water within said boiling mounted upon the] chamber, and means for; filling the unit I with water and providing space forthe ex pansion thereof under heat.

4.. A hot-water heating unit, embodying, in combination, a plurality of verticallydisposed tubes, a horizontally-disposed boiling chamber connected with the bottom of said tubes, another horizontally-disposed chamber connected with the top of said tubes; means for applying heat to the bot tom of said boiling chamber for heating water therein; means with water and providing space for the ex; pansion of'the water under heat;cmeans for making a water-circulating connection with said top chamber, a return pipe and means extending below the bottom of said boiling for filling the unit chamber and connected'to said returnpipe for causing water from said return pipe to befed in an upward direction into saidboiling chamber. 7 V 7 i Signed at the borough of Manhattan, city of New York, in the county of.
